.. _version-4.0:
4.0
===
:release-date: TBA
- Now depends on :mod:`amqp` 2.0.0.
- No longer depends on :mod:`anyjson`.
- New SQS transport
Donated by NextDoor, with additional contributions from mdk.
- Redis: Priority 0 is now lowest, 9 is highest.
(**backward incompatible**)
This to match how priorities in AMQP works.
Fix contributed by Alex Koshelev.
- Beanstalk: Priority 0 is now lowest, 9 is highest.
(**backward incompatible**)
This to match how priorities in AMQP works.
Fix contributed by Alex Koshelev.
- Redis: now supports SSL using the ``ssl`` argument to
:class:`~kombu.Connection`.
- Redis: Fanout exchanges are no longer visible between vhosts,
and fanout messages can be filtered by patterns.
(**backward incompatible**)
It was possible to enable this mode previously using the
``fanout_prefix``, and ``fanout_patterns``
transport options, but now these are enabled by default.
If you want to mix and match producers/consumers running different
versions you need to configure your kombu 3.x clients to also enable
these options:
.. code-block:: pycon
>>> Connection(transport_options={
'fanout_prefix': True,
'fanout_patterns': True,
})
- Exchange.delivery_mode now defaults to :const:`None`, and the default
is instead set by ``Producer.publish``.
- :class:`~kombu.Consumer` now supports a new ``prefetch_count`` argument,
which if provided will force the consumer to set an initial prefetch count
just before starting.
- Virtual transports now stores ``priority`` as a property, not in
``delivery_info``, to be compatible with AMQP.
- ``reply_to`` argument to ``Producer.publish`` can now be
:class:`~kombu.Queue` instance.
- Connection: There's now a new method
``Connection.supports_exchange_type(type)`` that can be used to check if the
current transport supports a specific exchange type.
- SQS: Will now log the access key used when authentication fails.
Contributed by Hank John.
- Added new :class:`kombu.mixins.ConsumerProducerMixin` for consumers that
will also publish messages on a separate connection.
- Messages: Now have a more descriptive ``repr``.
Contributed by Joshua Harlow.
- Async: HTTP client based on curl.
- Async: Now uses `poll` instead of `select` where available.
- MongoDB: Now supports priorities
Contributed by Alex Koshelev.
- Zookeeper: Transport now uses the built-in suport in kazoo to handle
failover when using a list of server names.
Contributed by Joshua Harlow.

:.. admonition:: Django transport migrations.
If you're using Django 1.8 and have already created the
kombu_transport_django tables, you have to run a fake initial migration:
.. code-block:: pycon
python manage.py migrate kombu_transport_django --fake-initial
- No longer compatible with South by default.
To keep using kombu.transport.django with South migrations
you now need to configure a new location for the kombu migrations:
.. code-block:: python
SOUTH_MIGRATION_MODULES = {
'kombu_transport_django':
'kombu.transport.django.south_migrations',
}
- Keep old South migrations in ``kombu.transport.django.south_migrations``.
- Now works with Redis < 2.10 again.

- RabbitMQ 3.3 changes QoS semantics (Issue #339).
See the RabbitMQ release notes here:
http://www.rabbitmq.com/blog/2014/04/02/breaking-things-with-rabbitmq-3-3/
A new connection property has been added that can be used to detect
whether the remote server is using this new QoS behavior::
>>> Connection('amqp://').qos_behavior_matches_spec
False
so if your application depends on the old semantics you can
use this to set the ``apply_global`` flag appropriately::
def update_prefetch_count(channel, new_value):
channel.basic_qos(
0, new_value,
not channel.connection.client.qos_behavior_matches_spec,
)
- Users of :mod:`librabbitmq` is encouraged to upgrade to librabbitmq 1.5.0.
The ``kombu[librabbitmq]`` extra has been updated to depend on this
version.

- Redis: Fixed serious race condition that could lead to data loss.
The delivery tags were accidentally set to be an incremental number
local to the channel, but the delivery tags need to be globally
unique so that a message can not overwrite an older message
in the backup store.
This change is not backwards incompatible and you are encouraged
to update all your system using a previous version as soon as possible.
- Now depends on :mod:`amqp` 1.4.4.
- Pidbox: Now makes sure message encoding errors are handled by default,
so that a custom error handler does not need to be specified.
- Redis: The fanout exchange can now use AMQP patterns to route and filter
messages.
This change is backwards incompatible and must be enabled with
the ``fanout_patterns`` transport option::
>>> conn = kombu.Connection('redis://', transport_options={
... 'fanout_patterns': True,
... })
When enabled the exchange will work like an amqp topic exchange
if the binding key is a pattern.
This is planned to be default behavior in the future.

This transport option is recommended for all users as it ensures
that broadcast (fanout) messages sent is only seen by the current
virtual host::
Connection('redis://', transport_options={'fanout_keyprefix': True})
However, enabling this means that you cannot send or receive messages
from older Kombu versions so make sure all of your participants
are upgraded and have the transport option enabled.
This will be the default behavior in Kombu 4.0.
- Distribution: Removed file ``requirements/py25.txt``.

the consumer without draining events.
.. _version-3.0.0:

=====
:release-date: 2013-10-14 04:00 P.M BST
:release-by: Ask Solem
- Now depends on :mod:`amqp` version 1.3.
- No longer supports Python 2.5
The minimum Python version supported is now Python 2.6.0 for Python 2,
and Python 3.3 for Python 3.
- Dual codebase supporting both Python 2 and 3.
No longer using ``2to3``, making it easier to maintain support for
both versions.
- pickle, yaml and msgpack deserialization is now disabled by default.
This means that Kombu will by default refuse to handle any content type other
than json.
Pickle is known to be a security concern as it will happily
load any object that is embedded in a pickle payload, and payloads
can be crafted to do almost anything you want. The default
serializer in Kombu is json but it also supports a number
of other serialization formats that it will evaluate if received:
including pickle.
It was always assumed that users were educated about the security
implications of pickle, but in hindsight we don't think users
should be expected to secure their services if we have the ability to
be secure by default.
By disabling any content type that the user did not explicitly
want enabled we ensure that the user must be conscious when they
add pickle as a serialization format to support.
The other built-in serializers (yaml and msgpack) are also disabled
even though they aren't considered insecure [#f1]_ at this point.
Instead they're disabled so that if a security flaw is found in one of these
libraries in the future, you will only be affected if you have
explicitly enabled them.
To have your consumer accept formats other than json you have to
explicitly add the wanted formats to a white-list of accepted
content types::
>>> c = Consumer(conn, accept=['json', 'pickle', 'msgpack'])
or when using synchronous access::
>>> msg = queue.get(accept=['json', 'pickle', 'msgpack'])
The ``accept`` argument was first supported for consumers in version
2.5.10, and first supported by ``Queue.get`` in version 2.5.15
so to stay compatible with previous versions you can enable
the previous behavior:
>>> from kombu import enable_insecure_serializers
>>> enable_insecure_serializers()
But note that this has global effect, so be very careful should you use it.
.. rubric:: Footnotes
.. [#f1] The PyYAML library has a :func:`yaml.load` function with some of the
same security implications as pickle, but Kombu uses the
:func:`yaml.safe_load` function which is not known to be affected.
- kombu.async: Experimental event loop implementation.
This code was previously in Celery but was moved here
to make it easier for async transport implementations.
The API is meant to match the Tulip API which will be included
in Python 3.4 as the ``asyncio`` module. It's not a complete
implementation obviously, but the goal is that it will be easy
to change to it once that is possible.
- Utility function ``kombu.common.ipublish`` has been removed.
Use ``Producer(..., retry=True)`` instead.
- Utility function ``kombu.common.isend_reply`` has been removed
Use ``send_reply(..., retry=True)`` instead.
